[Elecraft] Why is my K3 off frequency?

[Michael Walker]

If your Net Control station has an accurate enough ear to tell you are 12Hz
off frequency on an SSB net, I would ask him to align it for you.

On 80M, you may be only off frequency by a few hz.

12Hz at 50Mhz is really nothing.  If it concerns you, you will need to
align it with the correct alignment tools and a trip to a repair facility
with a calibrated frequency standard is in order.  If it was me, I wouldn't
worry about it too much.  You can remind your Net controller that that is
what the RIT control, is for on his radio.

If I remember correctly, the K3 accuracy is 5ppm and at 50Mhz that is +/-
250hz at 50Mhz.  It is only 15Hz at 80M.   If my assumption is correct or
PPM, your radio is within Spec.  I'm sure others will correct me if I
am wrong.
